Two identical 110 MWe high pressure FOSTER WHEELER PYROFLOW{reg_sign} circulating fluidized bed (CFB) boilers went into commercial operation in 1995. Both boilers generate 98.91 kg/s (785,000 lb/hr) of main steam t 174 bar (2,525 psig) and 540 C (1,005 F) with reheat steam at 540 C (1,005 F). Both were built to burn waste fuels. One unit, located in Colver, Pennsylvania, burns bituminous gob and the other unit located in Northampton, Pennsylvania, burns anthracite culm with a 20% mix of silt. A different type of ammonia injection system for reducing NOx emissions was installed in each boiler. An anhydrous ammonia injection system is used in the Colver plant and an aqueous ammonia direct-injection system is used in the Northampton plant. A performance optimization test was performed on both boilers prior to the commercial operation at the direction of and in accordance with the requirements of the Pennsylvania Regulatory Authority. In addition, boiler performance tests were run on both units to confirm operation in accordance with performance guarantees. The results of these tests are provided in detail in this paper. The resultant data provides a comparison in boiler operation between the two different categories of waste fuels fired in identical CFB boilers. The data also provides insight into the low emissions levels and limestone utilization capabilities of the CFB boiler.
